Specification of Letters Patent.

Patented July 24, 1906.

, a citizen -of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented new and useful lmrovement's in Accent and Expression Regu ating Means for Automatic Musical Instruments or Players, of which the following is a specification, reference being had to the accomp anying drawings forming a part thereof. The purpose of this invention is to provide improved devices for phrasing the music, including regulating the speed and controlling the intensity of the playing-action,.of an automatic musical instrument or player for the purpose of 'accenting the music and modify ing the tempo and expression or emphasis at different parts.

It consists of the features of construction set out in the claims.

In the drawings, Figure 1 is a planview of a portion of an automatic player, the upper part being broken away to show the devices underneath. y Eig. is a section at the line 2 2 on Ffm. 1, section extending also above the parts shown in that figure, cutting through the air-chamber of the pneumatic-action, which is partly broken away, showing the other parts. Fig. 3 is a section'at the line 8 3 on Fig. 2 looking upward. Fig. 4 is a section at the line 4 4 on Fig. 3. Fig. 5 is a detail plan view of apart of the stop board or table, showing certain modifications in. the speed regulating stop-action. Fig. 6 is a artly sectional rear elevation of these modified devices, section being made in vertical plane longitudinally through the valve-box. Fig. 7 is a section at the line 7 7 on Fig. 6.

rThe drawings show a familiar form of many elements of an automatic player, whichwill not be particularly described, but only mentioned for identification.

1 is the air-chamber ofthe pneumatic-action of a pneumatica]lyoperated automatic playerof the general type which employs pri-y mary pneuinatics 2 2 in such chamber for controlling the action of the motor-pneurnatics, which actuate the strikers for striking the keys, such riiotc r-piieuniatics and the connections between them and the primary pncuxnatics not being shcwn.

Tt -k #bci3 d l aff- Ictlac e1 cart. an ro is. a oi carry ing the perforated controlling-sheet (the latter not vbeing shown) are of familiar form. Any forni of' motor for rotating the rolls to cause them to propel the controlling-sheet may be employed, and any forni of devices for shifting the driving power so as to wind the sheet on one roll for playing and rewind it upon the other roll may be employed. There is shown in the drawings of such mech'- anism only the lever 5, which operates the shifting devices and is hereinafter referred to as the rewind-lever, and without reference to the particular form of suoli devices it is to be understood that the lever is moved to the right (in the plan view, Fig. 1) for connecting the power with the take-up roll for playing and to the left for connecting it with thev rewind-roll.

The wind-chest or main exhaust-chamber 8 is connected with the pneumatic air-chamber 1 through two passages 9 and 10, which are separately controlled by valves 1 1 and 12, both mounted in the box 13, from which a single passage or Connecting-tube 14 leads to the air-chamber 1. A governor 15 is interposed in the passage 9 between the wind chest and the valve-box. The passage 10 is uncontrolled except by the valve 12.` The two valves 1 1 and 12 being in the form shown in Fig. 2 adapted to slide to close their respective ports are arranged to be both oper ated by a rod 16, connected with the rear end of the rewind-lever 5 by means of an interposed lever 17, fulcrumed at its lower end on the back board 18 and at its upper end to said rear end of the lever 5, therod 16 being connected with the lever intermediate the ends,

the particular means for this connection being a fiat link 19, which is iexiblyand adjustably connected to the rod 16 by having a terminal lug 19a, through which the rod 16 extends loosely, the rod being threaded and provided with nuts 1.6a and 16b atopposite sides on the lug, with their ends toward the lug rounded so as to permit considerable freedom of movement at the joint thus formed. The rod 16 passes substantially air-tight through the end of the valve-box 13, and within the boX it passes through a stem 12a, which extends rigidly up transversely from the valve'12, and a stop button or collar 16 on therod 16 between said stem and the end of the valve-box through which the rod enters by encountering the stem moves the IOu valve 12 in direction Yto ,cover its port when the rod 1.6 is thrust inward. Said rod is positively'connected to the valve 11, so that it carries the 'latter valve positively withA it in itsI movement in either direction. Y y

is a rod parallel with the rod 16, which vextends I'in' through thev same end of'the valve-box and through the same stem 12a of the valve 12. On this rod are stops 20a and 20h, the former in position to stand against the stem 12a of the valve 12v when the said valv'e 12 `is entirely oifits seat, and at this position ofthe rod the stop 20b'is against the linner face of the end of the box through which the rod enters. The rod 20 is vguided in a cross-bar 13b in the'box, and it has also a third stop 20c, which stops against this crossbar 13b when the rod is thrust in a suflicient 1 distance to cause its stop 20a to carry the valve 12 into closed position over its port. Since the rod 16 passes loosely 'through the stem. 12u-that is, without operative engagement-the movement of the said valve 12 by the stop 20a when the rod 20 is thrust in, as described, is without effect upon the rod 16 or the valve 11, which is positively connected to said rod-that is to say, the valve 12 may be seated over its port b the inward thrust of the rod 20 while the va ve 11 stands wide open. on the valve 12 to retract it to open position and to yieldingly resist the closing'movement cranked shaft 31, `from which any asuitable train (not shown) may be understood as bein` employed to communicate power to the ms for driving them according to the adjustment of the lever 5 to the right or left. The motor air-chamber is connected with the wind-chest through two passages 32 and 33, which are separately controlled by valves 34tand 35, both mountedy in a box 36, from which a single passage or connecting-tube 37 leads to motor air-chamber. A governor is interposed in the passage 32 between' the wind-chest and the valve-box. The passage 33 is uncontrolled except by the valve35. The two valves 34 and 35 may be in form adapted to slide to close their respective ports. llor the ordinary action of the he valve over the ungove'rned port i, and the motor is operated only by 1 i air Aderived through the governed passage past' the valve For intensifying the actien oi' the motor 'for accelerating the time of A spring 21 is provided acting' the music the valve 35 may be opened more or less, thus adding to the force derived from the governed passage such amount as may be necessary, derived through the ungoyerned passage, which will drive the motor at any speed up to that which the maximum exhaust tension of the wind-chest lis adeuate to cause. When the driving connection is shifted to the rewind-roll for reversing the direction of travel of the controllingsheet over the tracker-board, the maximum speed of the motor may be used, no governing being necessary, because no playing is being done, and for that purpose the valve 35 is opened widewhenever the lever 5 is shifted to the left for'rewinding. It will be Iremembered that in the same casethat is,

during rewinding-"the communication from the wind-chest to the pneumatic playing-action should be entirely closed, because no playing is desired. I therefore connect the rod 16, which operates the expression-valves 11 and 12, with the valve 35 in such manner that the movement ofthe rod 16 for closing the valves 11 and 12 will move the valve 35 to wide-open position; but since the valve 35 must sometimes be opened more or less for accelerating the music when the valve 11 is not closed the connection of the rod 16 with the valve 35 is made by having the rod 26, .which constitutes the connection from the rod 16, extended through the stem 352L of the valve 35 without operative engagement therewith and providing on said rod 26, be-

yond the stem 35a, a stop-button 26a for engagin the stem to pull the valve open, but not a apted to prevent it from being opened by other means. A spring 39 is provided, connected in any convenient manner with the valve 35, reacting to hold said valve normally closed and adapted to yield for opening it to such extent as it may be forced by the movement of the rod 16 or other means. The rod 16 is connected with the rod 26 for operating the latter by the pull of the former and not otherwise, the connections consisting of an offset eye 26d on the rod 26, through which the rod 16 extends, a stopbutton 16al being fixed on the rod 16 behind the eye at such position that when the valve 35 is closed the eye encounters the button as soon as the rod 16 moved in direction for closing the valve 1 1, andthe further progress of suoli closing movement opens the valve 35 as much as the valve 11 ifs closed.

The valve 34 has a rod or stem 40 extending out through the end of the valve-box 36 and connected to the lever 41, which is lulcrumed at 42 on the rear side of the back board. Said lever extends up past the .rear end of the tempo-stop lever 43, which has at its forward end a tempo-stop inger 44, projecting up through a slot 59 in'the sto p-board. A spring 55, acting on the lever 41, tends to IOO IIO

hold the. 'valve 34 open and the tempo-stop finger 44 at the extreme left-hand limit of the slot 59, and the mor-ement of the stop toward the right closes the valve more or less, according to the distance and thereby enables the operator to control the amount of air drawn in thrfiugh the motor and the resultant speed of the controlling-sheet and the rate of playing up to the maximum speed for which the governor` 3S is adjusted. For temporary retard me'nt there is provided the retard-stop 56, which is a finger at the forward end of the 'l etard-lever 57, which is fulcrumed on the stud 5S, which also affords fulcrum for the tempo-stop lever 43. Said retard-lever 57 at its rear end extends past the upper end of the lever 41, thelever 57 being above the lever 43 and the retard-stop linger 56 being behind and extending higher than the tempostop finger 14. The forward end of the lever 43 runs under a ratchet-bar 52, which engaging said end of 'the lever holds it at the'position to which it is adjusted against the tension of the spring 55, the lever being disengageable from the ratchet-bar by depressing the tempo-stop finger, springing down the forward end of the lever 43. The lever 57 extends forward past the right-hand side of the tempo-stop finger, so that the latter oonstitutes a stop and limit for the movement of the retard-lever to the left, while permitting itto be moved without restraint farther to the right.

The operation of the tempo and retard stops will be understood from the foregoing description to be that the tempo-stop being moved to the right closes the valve 34 a distance corresponding to the ext-ent of such movement and being moved to the left permits the valve to be reopened by the reaction of the spring 55 and that the engagement of the lever 43 with the ratchet 52 prevents the spring 55 from retraoting the lever for openingvr the valve, while the tempo-stop stands at any position to which it lmay bevthus adjusted for regulating the general rate of playing suitably'to the music. The retard-stop may be moved farther to the right and held j ."for any length of time, thereby retarding the playing so long as it is thus held, and when released it Will be retracted by the spring 55, operating on the lever 41, and press against t e rear end of the lever 57; but only until the forward end'of said lever 57 oollides with the tempo-stop finger, so that after the temporary retardment the revious rate of playing determined by the a justment of the'tempostop is resumed Without attention on the art of the operator. For exceptional accelration the valve 35 may be opened more or less to give the motor-director ungoverned communication with the wind-chest, and for that purpose the rod'26, which operates this valve, extends through an eye 45, carried at the lower end of a lever-arm 46 of a rock-shaft 47, which is mounted on the under side of the stop-board and has at its forvA ard end a leverarm 48, connected with a stop-button 49,

y Which extends up through the stop-board, a

spring 50 being provided to uphold the button and yieldingly resist its depression. This spring is conveniently placed, as shown, operating on the lever-arm 46 to hold it in direction for upholding the button. ton 51 on the rod 26 at t-he side of the eye remote from thevalve--boXl is encountered by A stop-butthe eye in the movement of the lever-arm 46,

caused by de ression of the stop-button, and the valve 3 5 is thereby opened and held open as long as the button is depressed by the operator. rod 26 throughout the curved. path of movement of the end of the lever-arm 46 the e ye is offset from the end o'f a short link 52,Which is pivoted at the other end Ito the lower end of the lever-arm '46. It will be observed that by the coperation of the tempo-sto p and the accelerando-stop button 49 the operator having adjusted the tempo-stop for the rate of 'playing desired at any particular point in the music can momentarily or for a short time accelerate the music to any desired extent by depressing the button 49J and upon releasing the button the original rate of playing will be resumed, because the tempo-stop .an-d the position of the valve 34 remain unaffected by the ten'iporary opening of the valve 35 by the accelerando-stop button.

At all times when the stop on the forward end of the lever 5 stands at the right of its range of movement (see Fig. l) the take-up' roll is connected with the driving-train and rotated for propelling the controlling-sheet over the tracker-board for playing. At this position of said stop the rod 16 holds the valve 11 Wide open, and the stop-button 16" on said rod permits the valve 12 to stand 'wide open; but in ordinary operation of the player the accent or expression stop 25 is at the position for holding the rod 20 at the innermost position to Which it may be thrust in the valve-box and holding the valve 12 closed. In this ordinary position of the parts the pneumatic action'is ex osed to the governed air from the Wind-c est or main eX- haust-chamber, and the result is an intensity of stroke by the key-strikers, providing the softest expression of the music of which the instrument is capable With a given adjustment of the governing device. For increasing the force of the stroke and the intensity of the music the sto 25 is moved to the right more or less, accor ing to the increase or in tensity desired7 causing the valve 12 to be opened more or less in the same degree and 'adding to the force derived through the gov- For accommodating the eye to the IOC IIO

IIS

from the wind-chest to the air-chamber, according to the degree to which the valve 12 is thus opened, and when the valve is held wide open by the movement oit the stop 25 to the extreme limit of its range to the right the maximum intensity or loudness of playing is produced. AVlhen the lever 5 is shifted to the left for reversing the driving connection, shiti ng the power from the take-up roll to the rewind-roll and causing the controlling-sheet to be propelled in reverse direction over the tracker-board, the air communication from the wind-chest to the pneumatic action should be entirely cut off, because no playing action is desired, and it will be observed that this result follows automatically from the movement ot the take-up lever 5 to the left as necessary for reversingthe driving connection; because that movement thrusts the rod 16 inward to its bearing in the valve-box and carries both the valves 11 and 12 to closed position. When for an reason it is desired to interrupt the playi whether with or without reversing the travel'of the controlling-sheet, and to resume playing again,.the playing will be resumed with the same force or intensity as when it was interrupted, because the movement of the rod 16 for closing the valves 11 and 12 leaves the rod 20 unaffected in position, Vand when the `rod 16 is again withdrawn for openi ng the valves while the valve'll will open fully the valve 12 will only open back to the point to which i tihad u been set by the adjustment of the expression or accent stop-that is, the stem 12a will come back to the stop-button 20'L on the rod` 20 and no farther,

The lever 5 being connected with both the rod 16 and the rod 26 in such manner that the -movement of the lever for shifting the driving power to the rewind-roll operates for closing the valves 11 and 12 and for opening v the valve 35, only one-action is necessary to accomplish all that ,is re uisite for rewinding-to wit, (a) reversing t e driving connection, (t) cutting oit the'air from the pneumatic action, (c) giving the motornncontrolled communication with the wind-chest for the most rapid action, and these results are accomplished, as it will be observed,while retaining through the accelerando and tempo stops and their connections independent control of the two` valves 34land 35 and control ofthe valve 35without the reversion of the drivingconnection and without cutting off or affecting the communication between the wind-chest and the pneumatic-action. i

In Figs. 5, 6, and 7 ofthe drawings there is shown a modification of the accelerando and retard stop actions in order that the same stop operated in opposite directions'may/be employed'forfaccelerating and retarding and also that the tempo-stop vmay be adapted to retain its position without the necessity of a locking device, such as the ratchet 52. The construction illustrated in these 'ligures has in addition lto the tempo-valve 34 over'the governed air-passage 32 a second valve 84u, which slides from the opposite side of the port to close it, a spring 55, connected with the stem 34c of' the valve, operating to hold` the valve normally Oft its seat, leaving the port, so far as this valve is concerned, entirelyope-n. When the two valves 34 and 34a have their proximate edges together, wherever they may stand, the port is closed, and the distance between the proximate edges of the valves, if they are not together, determines the actual speed of playing. The tempo-stop connections are adapted to set the valve 34 at anyposition with any degree of opening and `the retard-stop connections are adapted to draw the valve 34 more or less toward the valve 34 when the latter is at any openposition. For this purpose two levers 43a and 57 are mounted upon the same 'fulcrum 58 on the under side of the stop-board., said levers having at their forward ends upwardly-protruding stop-tingers 44 and 56, respectively, which, however, both protrude through the same slot 59 instead ot through different slots, as in the other construction, standing alongside each other in the slot, the stop-finger 44 being at the left and the stop-'finger 56 at the right. At the rear end the lever 43EL engages a slot 41b in the upper end of a lever 41a, fulcrumed at 42 on the back board, and to said lever 41a intermediate its fulcrum and the engagement of the lever 43a therewith the rod 40 is pivotally connected, as in the other construction, said rod engaging the stem 34k of the valve 34, as in the other construction. The arrangement of the parts is such that when thestep-tinghr 44 occupies a position at about the middle of the segment-slot 59 the valve 34 is over the port of the passage 32, completely closing the same, and the movement of the stop-iinger 44 to the left, it will be seen, will uncover the port. T he lever 57a at its rear end projects alongside of the upper end of a lever 60, which 'is also tulcrumed at 42, and intermediate its fulcrum and the point of contact with. the lever 57*L is connected by the rod 40*1 with the stem 34" of the valve 34a. rl`he arrangement of the -parts is such that when the stop-finger 56 to retract the valve 34a from oft hthe port,

holds the upper end ofthe lever against the rear end of the lever 57a when said valve 34 is entirely ofi the port, as shown in Fig.y 6. When, therefore, the two stop-fingers 44 and 56 are together at the middle of the slot 59 the valve 34 completely cl'oses'the port,

, and the valve 34 is completely ofi of-it, but

IOC

the two valves are in contact at their oppositel edges. It now the tempo-stop 44 is moved to any distance to the left to open the valve 34 Jfor anyt desired speed, the operator by moving the stop-finger 56 more or less to the left approaching the stop-finger 44 will cause the valve 54a to follow the path taken by the valve 34 more or less and cover more or less ofthe port which was uncovered by such movement of the valve 34, thus reducing the speed for the time being, and while the stopnger 56 is held at such position according t0 the approach of the two stop-fingers 44 and 56, which corresponds to the approach of the two valves 34 and 34a. In order that the stop 56 and its connections may also operate the valve 35 for acceleration, there is fulcrumed at 47a on the back board a lever 46, which at the upper end extends past the rear end of the 'lever 57a at the opposite side thereof from the lever and at'the lower end is forked or slotted, as seen at 46", and has the rod 26 passing through its slot or fork-notch, a stop 51 being provided on the rod 26, as in the other construction, at the side of said lever 46a opposite the valve-box, so that the movement of said lever at the upper end in the direction corresponding to the movement of the stop-finger 56 to the right will cause the lower end of said lever 46a to act against the stop 51 for pullingthe rod 26 and moving the'valve 35 off its seat against the retraction of the spring 39. The action of the rod 26, valve 35, and spring 39 is in all respects precisely the same as in the first above-described construction when said rod 26 is actuated by the lever-arm 46 of the rockshaft 47 upon the depression of the accelerando-button 49; but this action, it will be observed, is produced by moving the stopnger 56 in the lslot 59 in the opposite direction from that in which it is moved in the same slot from the middle pointl thereof for retarding. Thus the stop-finger 56 becomes both the retard and accelerando stop, moving in one direction for one purpose and the opposite direction for the other purpose, its movement to the left for retarding being such as at all times to indicate by -its distance from the stop 44 the extent of opening ofthe valve and its movement in the opposite direction having no effect upon the tempo stop or valve.
